A Roundhouse Fuck is when you and a person of the opposite sex strip down and prepare for a sexual experience. On top of a bed, the women puts herself in doggy style fuck position sticking her vagina out for the man. Next the man will insert his penis into the womens vaginal quarters. The last step involves the women still present in her doggy style position rotating herself 360 degrees multiple times until climax is reached. The mans job is to hop around behind the women on the bed while she is rotating after each insertion. In other words, the man is moving in the same rotation the women is creating a continuous circle of sex.
